Delta is making a yuuugeeee mistake IMO, not because DTW is better suited, but because MSP is a huge money maker. There is a huge number of fortune 500 companies there (per capita at least) that bring in big bucks and high valued customers. Apparently Delta figures, just keep the frequency, reduce the size and call it good...watch when "the others" take over a large portion and Delta will be left scratching their heads.
